New Methods for the Characterisation of Refuse Derived Fuels and Waste
Two different ways of utilisation evolved in the combustion of waste. On the one hand untreated waste is disposed directly in mono-incineration plants, exploiting only part of the energy contained. On the other hand waste may be pretreated such that high calorific components can be separated and combusted separately with higher efficiency or better energy recovery. These are the so-called Refuse Derived Fuels (RDF).
The continuously decreasing availability of fossil fuel resources leads inevitably to increasing prices and bottlenecks in the conventional energy supply.
In that light, the aspect of energy recovery from waste and refused derived fuels (RDF) becomes more important all over Europe. The use of these fuels conserves fossil resources and is an important step towards sustainable energy economy. Especially for the Member States which joined the European Union in 2004 and 2007 this requires considerable Investment in waste management.
The primary goals must be to avoid any landfill of untreated municipal waste and to establish incineration and utilization capacities complying with European standards.
RDF is produced from untreated waste and may substitute fossil fuel in several thermal processes. For example in Germany 47 % of the waste input (6,4 m tons p.a.) is combusted in form of RDF. In 2009 the incineration rate (thermal utilization) of municipal waste amounted 33.6 % in Germany. In the Eastern European accession countries this value is between 0.1 and 12 %. Therefore waste-to-energy concepts become a central element in the European waste management. Compared to fossil fuels the compositions of wastes and RDF are subject to larger fluctuations. Depending on the area of application additional and improved procedures for the characterisation of alternative fuels are needed. Examples include the behaviour of volatile release and the actual heat transfer rates during combustion, especially the flight characteristics of RDF particles in coal fired co-incineration.

Current Developments in European Waste-to-Energy
© TK Verlag - Fachverlag für Kreislaufwirtschaft (12/2015)
Europe’s future Circular Economy package should be ambitious in minimising landfilling of recyclable and recoverable waste, in order to maximise the use of waste as a resource. It should take a holistic approach that considers supply of raw materials as well as supply of secure and sustainable energy, which is an important part of the European Energy Union. This approach would be in line with Better Regulation and would benefit the environment, jobs and growth in Europe.
Bedeutung der Qualitätssicherung für Solid Recovered Fuels am Beispiel des EU-Projektes RECOMBIO
© IWARU, FH Münster (2/2013)
Biogene Brennstoffe werden in Deutschland überwiegend in EEGMonoverbrennungsanlagen häufig im reinen Verstromungsmodus energetisch verwertet. Deutliche Effizienzsteigerungen sind nur bei der Mono- und Mitverbrennung in Kraftwerksprozessen mit hohen Dampfparametern bzw. in Kraft-Wärmekopplungsanlagen (KWK-Anlagen) möglich.

Industrial Pellet from Logging Residues and Other Woody Waste Products

The European Union decided in its Directive on the Promotion of the Use of Energy from Re-newable Sources to cover at least a 20 % share of energy from renewable sources in the Com-munity’s gross final consumption of energy in 2020. Among the renewable sources solid bio-mass plays the most important role. This leads towards a growing demand of machines and systems for the preparation of woody biomass fuels. The Komptech GmbH is developing such solutions.
Study on the Suitability of the Different Waste-Derived Fuels for End-of-Waste Status in Accordance with Article 6 of the Waste Framework Directive - Second Interim Report
© Eigenbeiträge der Autoren (8/2011)
The objective of this study is to provide detailed information and analyses to the European Commission on all the relevant aspects needed for proposing the end-of-waste status of fuels derived from waste. It analyses the suitability of different waste-derived fuels (WDFs) for obtaining the end-of-waste status in accordance with the requirements set out in Article 6 (1) of the Waste Framework Directive.
